The three English letters of LED, for many people who are concerned about the display industry, are probably the most frequently appeared words in recent years. Many people in the industry call 2010 the year of LED, and LED is also known as the \"artifact\" that can carry the banner of display innovation and let the display enter the new era and revive the glory of the past. Of course, if you agree, there will be doubts. Even with all the brilliance of the LED backlight technology, skeptical people still believe that in the face of the falling prices of notebook computers and the sharp shrinking of DIY, the market share of monitors is much lower than before. . Plus, the monitor\'s update rate is rather slow. Even if LED can become a technology recognized by everyone, it will not suddenly eliminate the old models to meet its arrival.

With the improvement of LED full-color display technology and large-screen splicing technology, LED full-color display products are becoming more and more mature, and are widely used in stage background display and live broadcast display, becoming an essential set and color effect tool for large-scale venues. . Through the continuous transformation of the large screen, the LED full-color display can deeply express the theme and style of each program of the stage performance, and is an indispensable tool in the design of stage art.

At the same time, the improvement of its brightness and dot pitch performance has made a major breakthrough in the application of LED screens in indoor and outdoor places. In addition, the bendable nature of some LED displays makes product deployment, special effects realization and special applications possible. In recent years, the widespread adoption of LED full-color displays in large-scale performances such as the Olympic Games, World Expo, and CCTV Spring Festival Gala has driven the demand for LED full-color displays in the stage background market. Not only that, but in recent years, LED displays have been increasingly used by municipal departments for government affairs disclosure and in important municipal places such as urban main roads, financial and commercial centers, large squares, subways and other highly developed urban yellow areas and important municipal venues. The broadcast of public propaganda videos not only enhances the government\'s image but also shapes the city\'s brand. At present, many provinces and cities in my country are vigorously promoting the use of LED full-color display screens in municipal public information display and display projects, opening up new markets for related manufacturers.

Some people also predict that the upper limit of LED life in the future will be infinite. With the recent improvement of LED heat dissipation technology, high-power LED street lights, flood lights and other LED high-power lighting fixtures for outdoor lighting have been industrialized and started to be widely used. Stage lights and studio lights for indoor lighting that require high color temperature and color rendering have also been mass-produced and put into use. The T8, T5, T4, lamps of general lighting with the largest application range and the largest consumption, and the screw bulbs that replace incandescent lamps and energy-saving lamps have been serialized to form a series with a service life of up to 50,000 hours. LED lighting has entered a period of rapid development.

Comparing the LED with ordinary incandescent lamps, spiral energy-saving lamps and T5 trio color fluorescent lamps, the results show that the luminous efficiency of ordinary incandescent lamps is 12lmW, and the lifespan is less than 2000 hours. The fluorescent lamp is 96lmW and has a lifespan of about 10,000 hours, while a white LED with a diameter of 5 mm can theoretically exceed 150lmW and have a lifespan of more than 100,000 hours.
